Cosmic dust

When the Earth formed 4.5 billion years ago, its phosphorus probably sank into the Earth’s molten core due to its distinct chemical properties. However, “phosphorus” is essential for life and is found in DNA, RNA, and other biologically important molecules. Therefore, it is possible

According to the Big Bang, new research by researchers shows that very small extraterrestrial particles known as “cosmic dust” may have delivered phosphorus to the Earth’s atmosphere. Where a set of chemical reactions reconstitutes the element into biologically useful forms — metal phosphates and phosphates — and eventually land on the earth. After entering the atmosphere, air friction causes dust to evaporate. And the melting is called erosion. New research is based on previous research in which meteorite fragments were heated to the size of dust to simulate erosion, and the researchers found that “phosphorus-containing molecules” were released. Computational modeling of this process confirms dust as an important source of phosphorus on Earth. Researchers have developed a network of chemical reactions with specific processes during which dust erosion can produce biologically beneficial molecules of phosphorus.
For example, the density of dust in an interstellar medium is a local bubble of about ten to the negative view of 6 grains per cubic meter, with a mass of about 10 grains having a mass of minus 17 kilograms. Observe Space Dust in two ways: optical telescopes or radars. Now, thanks to researchers at the University of Tokyo, they have developed a new method combining both methods using radar observations. “Interstellar dust, or dust, helps astronomers study the activity and arrangement of comets, asteroids, and meteors.” Interstellar is practically invisible. However, every day about 1,000 kilograms of it falls to the ground in the form of tiny meteors that appear as bright streaks in the night sky.
New research has shown for the first time the origin of microscopic meteorites that cause dust. Recent research has shown for the first time that some of the dust that covers the solar system and Earth comes from the star belt between Jupiter and The origin of these dust remained unknown for a long time, and researchers believed that the study of the mineral and chemical properties of these materials could indicate their place of origin.
